Making heads or tails of unemployment

Statistic of the day:

Number of SC counties whose non-seasonally adjusted unemployment rate lowered in March 2006: 46

Number of SC counties whose non-seasonally adjusted unemployment rate lowered in March 2005: 46

"A drop in unemployment rate for every county in the state is one more sign that we're moving in the right direction with respect to our economy." - Mark Sanford

Just like it was last year, right?

The fact is, SC's unemployment rate went up in March, because fewer jobs were gained than usual for the month. So either Sanford doesn't understand the process/purpose of seasonal adjustment, or he's trying to pull a fast one on taxpaying voters. I wonder which one it is...
